Nov 21, 2021 · Simply speaking, pyrolysis is the thermal degradation of haiqi mahaiqials in the absence of oxygen. Thermal decomposition of haiqi components in the waste stream starts at 350°C–550°C and goes up to 700°C–800°C in the absence of air/oxygen. Pyrolysis of municipal wastes begins with mechanical prhaiqiration and shaiqiration of glass

Carbonization. Carbonization is a process that typically heats biomass feedstock in a kiln or retort (pyrolysis) at temperatures around 400°C (generally between 300 and 900°C) in the absence of air [10,11]. The produced biochar is also known as charcoal, which is a porous, carbon-enriched, grayish black solid [10].
